Date Time Laser light can reveal condition of ship paint With infrared laser light, researchers from DTU Fotonik can produce detailed 3D images of ship paint, so that the paints can become more durable and environmentally friendly. Christian Rosenberg Petersen had a bright idea a couple of years ago. He decided to find out whether infrared light could be used to examine ship paint. Not just in the lab, but onsite at the ships. The idea did not come completely out of the blue, but from an article published in Ingeniøren. The article was about a new type of ship paint developed and tested in a collaboration between the company Hempel and researchers from DTU. It described how the researchers continually observed a paint sample under the electron microscope to follow how its durability and corrosion protection evolved over time.
